Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567716, here are decompositions:

7 + 31567709 = 31567716
17 + 31567699 = 31567716
23 + 31567693 = 31567716
29 + 31567687 = 31567716
43 + 31567673 = 31567716
67 + 31567649 = 31567716
73 + 31567643 = 31567716
79 + 31567637 = 31567716

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.175.100.

Address: 1.225.175.100
Class: public
IPv4-mapped IPv6: ::ffff:1.225.175.100

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
